Answer:
x = 3 and x = -12
Step-by-step explanation:
To solve an absolute value equation, you create two equations, one where the right side is negated and one where the right side isn't:
| 2x + 9 | = 15 becomes:
2x + 9 = 15 and 2x + 9 = -15
2x = 6 and 2x = -24
x = 3 and x = -12
Why this works is that |-x| and |x| will both be equal to 0. Remember that absolute value is the distance a number is away from 0.
Answer:
4:00. I am sure that it is 4 o clock!
Step-by-step explanation:
it is 4:00
3( -4 ) = y - 5
-12 = y - 5
y = -7
Answer:
B
Step-by-step explanation:
Plug in:
y = 2
x = 0
2 x 0 = 0 - 1 = -1
2 is greater than / equal to -1
